Evolve New Zealand charms are designed to reflect our unique culture and spectacular landscapes. This highest quality 925 Sterling Silver collection features traditional cultural symbols and iconic kiwi designs. Each treasured design has a special meaning. Design Inspiration: New Zealand’s National Fern. We are excited to announce our support of Netball New Zealand’s 2010/2011 campaign in the lead up to the Commonwealth Games. Each Silver Fern now wears an Evolve New Zealand bracelet with the Silver Fern charm. As the Silver Ferns meet goals and complete training modules they will add Evolve charms to celebrate their achievements.
